## ESPnet2 LID model

### `espnet/geolid_combined_shared_trainable`

This model was trained by Qingzheng-Wang using geolid recipe in [espnet](https://github.com/espnet/espnet/).

### Demo: How to use in ESPnet2

Follow the [ESPnet installation instructions](https://espnet.github.io/espnet/installation.html)
if you haven't done that already.

```bash
cd espnet
git checkout 77e4293952083b9e32bc19a5ddc19efe45e70e4a
pip install -e .
cd egs2/geolid/lid1
./run.sh --skip_data_prep false --skip_train true --download_model espnet/geolid_combined_shared_trainable
```
